Nextcloud Tasks
What Nextcloud Tasks is
Nextcloud Tasks is a free, open-source task manager for self-hosted Nextcloud servers and the web. It syncs tasks across devices and lets users edit titles and descriptions, set start and due dates, and choose each task’s priority and status. Recurring tasks, reminders, subtasks, and calendar sync are supported. Smart collections group important, current, and upcoming tasks; users can also drag tasks to other calendars. CalDAV connections let it sync with compatible apps, including Apple Reminders, 2Do, DAVx5, GNOME Todo, Kalendar, Thunderbird Lightning, BusyCal, and Planify. A server administrator enables the app from Nextcloud’s Apps section. The listing identifies Tasks 0.18.1 as compatible with Nextcloud versions 31 through 35. It is licensed under AGPLv3+. The app relies on the ETag HTTP header, so changes to that header can trigger false conflict reports; some anti-tracking browser extensions may need an exception. The listing links to a community forum and GitHub for discussion and problem reports.
